Potato Bacterial Wilt
02 Oct 2022
Ink painting/drawing of potato bacterial wilt, caused by Ralstonia solanacearum.
The painting shows two potato stems with wilted leaves. The leaves remain green whilst wilted, unlike the fungal/oomycete wilts. There is a cut in half potato at the base of the left stem, with a brown stained vascular ring.
